Need help to set up BV107_1 WiFi to Serial

I bought this about two weeks ago from eBay.
And after going through the step by step procedure, I couldn't make it work. So I thought the seller might help me out if I ask him, but unfortunately it turned out useless.

He says "what did you expect would happen?".
What kind of question is that? Of course I wanted to transfer and receive data via this module. I did reply to him but he didn't reply me back so I need help from you. If know how to set it up please let me know in the comment below. Thanks :)
